Features

Self tapping capability: Forming its own thread in thin sheet metal eliminates the need for pilot holes in many installations, reducing assembly time and equipment steps.

Head geometry: Serrated Indented Hex Washer Head distributes clamp load, resists cam-out under torque, and maintains a flush seating profile in sheet metal assemblies.

Drive type: Unslotted drive requires a hex or compatible driver, providing stable engagement and reducing tool slippage during high-torque installations.

Finish and corrosion protection: Zinc plating with bake enamel enhances resistance to moisture, humidity, and routine environmental exposure, extending service life in indoor and light outdoor applications.

Material suitability: Steel core delivers robust shear and tensile performance for fastenings in metal enclosures, panels, and automotive interiors where moderate loading is expected.
